Susceptibility of different larval instars of a field colony of the American bollworm, Heliothis zea (Boddie) to some organophosphorus insecticides [Egypt]

The 2nd, 3rd, 4th and 6th instar larvae of a field colony of the American bollworm, Heliothis zea (Boddie) were treated topically with acetone solution of malathion, mehtyl parathion and dimethoate. The results revealed the following: The sixth larval instar was more susceptible to malathion as comp...

Summary:The 2nd, 3rd, 4th and 6th instar larvae of a field colony of the American bollworm, Heliothis zea (Boddie) were treated topically with acetone solution of malathion, mehtyl parathion and dimethoate. The results revealed the following: The sixth larval instar was more susceptible to malathion as compared with the other instars. For methyl parathion and dimethoate the second larval instar the most susceptible one. Susceptibility of larval instars to the three tested insecticides could be arranged descendingly as follows; 6th, 5th, 4th, 3rd and 2nd for malathion; 2nd, 4ht, 6th, 3rd and 5th for methyl parathion and 2nd, 4th, 3rd, 6th and 5th for dimethoate.
